Frontal groove distinct. Antennae long, filiform, 12-jointed; scape 

 short, about twice as long as broad, first funicular joint as broad 

 as long, remaining joints cylindrical, the second distinctly longer 

 than the third. Thorax elongate; mesonotum prominent, with 

 distinct Mayrian furrows. Petiole and postpetiole shaped some- 

 what as in the worker but less convex dorsally, the former without 

 a ventral tooth. Gaster long and narrow. Legs long and slender, 

 the femora not dilated. 



Finely punctate, but the punctures more distinct than in the 

 female, so that the surface of the body is somewhat less smooth 

 and shining; mandibles smooth, sparsely punctate.
